Keselowski drove to a fifth-place finish in Sunday’s fourth race of the 2017 Monster Energy NASCAR Cup Series season.

But his Team Penske Ford did not pass inspection following the race. Keselowski’s car failed weight and measures.

As outlined in NASCAR’s new deterrent and penalty system the violation is a L1 and could carry a 10-40 point deduction, a $25-$75,000 fine and anywhere from a 1-3 race suspension for crew chief Paul Wolfe.
